The 44-year-old actress - who has a two-year-old daughter Nahla with ex-boyfriend Gabriel Aubry - would love to expand her family further but knows her advancing years mean it could be difficult.
She said: "I`d love morechildren. I`m 44, so who knows how much longer I can wait?"
As well as wanting morechildren in the future, Halle - who is believed to be dating her `Dark Tide` co-star Olivier Martinez - is planning to scale back her working commitments in order to accommodate her daughter`s needs and give the youngster a more stable environment as she gets older.
She said: "You make time for what`s important. She`s not yet three, so I take her with me. Once she`s five or six in school, I`ll have to make a change."
Though she is no longer with Gabriel, Halle insists she has no worries about the future because suffering from diabetes - where the body struggles to deal with the production of insulin and regular blood sugar levels - for over 20 years means she is used to looking after herself.
She told the New York Post newspaper: "I`m OK. I`ll always be able to take care of myself. Look, I`m a diabetic who also must watch my food. No pasta, no carbohydrates. I`m used to watching over myself."
